Today (and every day) I'm thankful for dishwashers and dishwasher inserts.
Every day, Alice and Katherine come home from day care with three or four used bottles apiece, each of which needs washing. Each of Alice's Medela brand bottles has three parts, and each of Katherine's Dr. Brown's brand bottles has five parts. The bottles fit nicely in the top rack of the dishwasher, and the other bottle parts (nipples, rings, valves, etc.) fit nicely in the dishwasher insert, as do the pacifiers.
My quality of life has vastly improved since I had the insight that I do not, in fact, need to wash the bottles individually by hand, and I am thankful.
